This article illustrates how the implementation of the EPBD in the UK has interacted with the CEN EPBD-related standards. The focus is on the UK story, but the some of the opinions and perspectives reflect discussions with technical advisors and civil servants in other countries. I was quite close to some of the decisions and the reasoning behind them but more distant from others. So, some of the views expressed are inferences, sometimes from 15 or so years ago. It is a personal perspective and in no way an official one: interpretations, including misunderstandings and errors are mine.
The EPBD was approved at the end of 2002 and entered into force early in 2003, by which time EU Member States needed to enact laws and regulations and develop administrative procedures. In some circumstances this could be delayed until early in 2006.
Some of the requirements of the Directive overlap with or can be implemented through pre-existing national procedures and regulations and procedures, and the Directive allows Member States flexibility in their compliance routes. Regulatory energy performance requirements were more highly developed on some countries than others. Where they existed, they were almost exclusively in the form of minimum performance requirements for specific elements of buildings, rather than the whole-building approach required by the Directive. The performance data for these elements was generally available from manufacturers or could be readily calculated. Calculations of expected annual energy consumption were used during the design of some buildings but were rarely applied to individual existing buildings (there was an informative system of “good practice” benchmarks for measured consumption in some countries).
